Assessment of the Water Quality in the Salt River Prior to Its Impoundment in Anderson and Spencer Counties,Kentucky.

摘要

Monthly water samples were taken and analyzed to determine the water quality of the Salt River in Anderson and Spencer counties in Kentucky prior to the river's impoundment. Sediments from the area watershed were analyzed by total acid digestion,barium chloride extraction,and aqueous extraction methods. Rainwater and runoff water were collected and analyzed for major cations and anions from two sites in the watershed. Calcium and bicarbonate in the Salt River originate from weathering of calcite,although mole ratios of these two ions suggest that weathering of magnesium carbonates also contribute bicarbonate to the water. High levels of sulfate in rainwater indicate some of this anion may be introduced into the area watershed by atmospheric precipitation.
